OBJ_BUCH-1478-001.book Page 17 Friday, July 1, 2011 8:48 AM
Measurements possible
– In concrete/reinforced concrete
– In brickwork (bricks, porous concrete, foam concrete, aer-
ated concrete, lime-sand brick)
– In light construction walls
– Under surfaces such as stucco, tiles, wallpaper, parquet
flooring, carpet
– Behind wood, gypsum board
Special Measuring Cases
Based on the measuring priniciple, unfavourable conditions
can influence the measuring result, for example:
– Multi-layered walls
– Empty plastic pipes and wood beams in hollow spaces and
light construction walls
– Objects running inclined in walls
– Moist walls
– Metal surfaces
– Hollow spaces in a wall; these can be indicated as objects.
– Closeness to equipment that generates strong magnetic or
electromagnetic fields, e.g. radio base stations or genera-
tors.

Initial Operation

Protect the measuring tool against moisture and direct
sun light.
Switching On and Off
Before switching the measuring tool on, make sure that
the sensor area 9 is not moist. If required, dry the meas-
uring tool using a soft cloth.
If the measuring tool was subject to an extreme tem-
perature change, allow it to adjust to the ambient tem-
perature before switching on.
Switching On
– To switch on the measuring tool, press the On/Off button
15 or the start button 11.
– LED 17 lights up green and the start display is indicated for
4 s on display 16.
– When no measurement is carried out and no button is
pressed for 5 minutes, the measuring tool switches off au-
tomatically. In the "Settings" menu, you can change the
"Cut-off time" (see "Cut-off Time", page 19).
Switching Off
– To switch the measuring tool off, press the On/Off button
15.
– When switching off the measuring tool, all settings are re-
tained in the menus.
Switching the Audio Signal On/Off
The audio signal can be switched on/off with the audio signal
button 13. In the "Settings" menu, you can select the type of
signals in the "Tone signal" submenu (see "Tone Signals",
page 19).

Prev. Concrete Universal
Position the measuring tool against the wall and move it over
the wall in the direction of travel (see "Method of Operation",
page 16). Measured results are indicated on display 16 after
a minimum measuring distance of 10 cm. To ensure correct
measurement results, move the measuring tool slowly and
completely over the assumed object in the wall.
If the measuring tool is lifted away from the wall during a
measurement or not operated (moving the device or pressing
a button) for more than 2 minutes, the last measured result
remains on the display. "Hold" appears on the sensor-range
indicator c. When the measuring tool is placed against the wall
again, moved, or when the start button 11 is pressed, the
measurement starts anew.
When LED 17 lights up red, an object is in the sensor range.
When LED 17 lights up green, no object is in the sensor range.
When LED 17 flashes, a "live" object is in the sensor range.
Display Elements (see figure A)
If an object is under the sensor, it will appear in the sensor
range c of the display. Depending on size and depth of the ob-
ject, identification of the material is possible. The object
depth l to the upper edge of the found object is indicated in
the status line.
Note: Both the indication of the object depth l as well as the
material property m refer to the object pictured black in the
sensor.
The indication of the object material m can represent the fol-
lowing characteristics:
– Magnetic, e.g. reinforcing steel
N
S
– Non-magnetic, but metal, e.g. copper pipe
N

– Non-metal, e.g. wood or plastic

The indication of "live" wires n can represent the following
characteristics:
– "Live"
Note: For "live" objects, no further characteristic is dis-
played.
– ? Not definite whether "live" or voltage-free
Note: Three-phase mains wiring are possibly not detected as
"live" conductors.
